Supraspinatus Muscle Research Paper

Four muscles that are attached to the shoulder blade make up the rotator cuff. These muscles work together to ensure the shoulder moves and rotates properly. If the muscles become inflamed or torn, you will struggle

DOI: 5/8/2016. Patient is a 48-year old male maintenance operator who sustained a strained shoulder when he was throwing waste metal into a bin.The patient was subsequently diagnosed with left shoulder impingement syndrome with massive tear of the supraspinatus and infraspinatus tendons. MRI report dated 5/28/16 revealed suboptimal examination; massive full-thickness rotator cuff tear involving the entire supraspinatus and infraspinatus tendons with severe medial retraction beyond the level of the glenoid measuring approximately 6.2 cm. Severe fatty atrophy and loss of muscle bulk in the supraspinatus and infraspinatus muscles; large glenohumeral joint effusion with fluid in the subacromial/subdeltoid bursa and subcoracoid bursa; mild to moderate degenerative changes of the glenohumeral joint; severe acromioclavicular joint arthritis with

RCT is a common disease. According to general population surveys, the prevalence of rotator cuff tear is 25 % in those older than 50 years of age and 20 % in those older than 20 years of age (1). The rotator cuff is a group of 4 muscles and their tendons supraspinatus, infraspinatus, teres minor, and subscapularis (2). These muscles connect the upper-arm bone, or humerus, to the shoulder blade. The important job of the rotator cuff is to keep the shoulder joint stable. RCT can be caused by degenerative changes, repetitive micro-traumas, severe traumatic injuries, and secondary dysfunctions. Falling on an outstretched hand, unexpected force when pushing or pulling or during shoulder dislocation can cause traumatic injury to the rotator cuff.

The rotator cuff refers to the group of muscles and tendons in your shoulder that connects your shoulder blade to your upper arm.

There are many more terms and concepts in throwing a baseball then the wind-up, cocking, acceleration, and the follow through. There is also the stride, your pelvis, rotation, deceleration, force, gravity, resistance and speed. (Maranowski). Within the shoulder, there are three major bones used. They are the clavicle, humerus, and the scapula. Another major component of the shoulder while throwing is the rotator cuff. The rotator cuff is made up of four small muscles which are the subscapularis, supraspinatus, infraspinatus, and the teres minor. The main responsibility of the rotator cuff is for the stability of the shoulder joint. It holds the humeral head in the glenoid socket during early abduction while throwing. (" biomechanics of," ).

Millions of people across the United States suffer from either Bursitis or a rotator cuff injury every year. Although sometimes the two can be misconceived, they are very different in all actuality. Bursitis is the inflammation or irritation of the bursa. A bursa is a fluid-filled sac used as a bumper near the joints to reduce friction. There are many bursae located in your body, some of which being in the hip, shoulder, wrist, and elbow. However, a rotator cuff injury only affects the shoulder area of the body. The “rotator cuff” is composed of the supraspinatus, infraspinatus, subscapularis, and teres minor muscles. There is only one main way to be diagnosed with Bursitis and it happens when you overuse a joint in sports or on the job. You can put the bursa under pressure for a long time, thus causing the bursa to become inflamed.

The rotator cuff is a group of 4 muscles, the supraspinatus, infraspinatus, subscapularis, and the teres minor. These muscles helps to lift your shoulder up over your head and also rotate it toward and away from your body. Unfortunately, it is also a group of muscles that is frequently injured by tears, tendonitis, impingement, bursitis, and strains. The major muscle that is usually involved is the supraspinatus muscle. Rotator Cuff Injuries are usually broken up into the following categories.

Painful arc syndrome (rotator cuff tendinitis, tear or impingement syndrome): Painful arc syndrome is a condition characterized by pain in part of the ROM, between 45 and 160 degrees. Bicipital tendon rupture: Bicipital tendon rupture is frequently diagnosed in association with rotator cuff disease as a component of the impingement syndrome. Glenohumeral adhesive capsulitis (frozen shoulder or pericapsulitis): Adhesive capsulitis is a condition of uncertain etiology characterized by progressive soft tissue restriction of both active and passive shoulder motion (Huang, et al. 2012 and Brauer et al. 2013).

Supraspinatus tendonitis typically occurs when there is an impingement of the supraspinatus muscle of the shoulder joint between the acromion as it passes by the acromion and humerus head. In response, the supraspinatus tendon and the contiguous peritendinous soft tissues become inflamed. The supraspinatus is a muscle located in the supraspinatus fossa of the scapula located in the shoulder and is largely affected by supraspinatus tendonitis. The supraspinatus allows for the abduction of the shoulder and its insertion is the greater tuberosity of the humerus. Tendonitis is the inflammation of a tendon and commonly occurs in the elbows, knees, and shoulders. Therefore, supraspinatus tendonitis is the inflammation of the supraspinatus. This condition is a very common inflammatory problem because it can be caused by the abduction of the arm, which is involved in many sports and activities.

The shoulder is a ball and socket joint which allows it a flexion and extension motion.

Lateral ankle ligament frequently go into inversion or hypersupination as the ankle undergoes abnormal plantar flexion, inversion, and internal rotation in the weight-bearing position. Hypersupination causes damage to lateral ligaments of ankle which further leads to development of lateral ankle

The suprahyoid muscles include the digastric, mylohyoid, geniohyoid, and stylohyoid muscles (19-21). All suprahyoid muscles bring to elevate the hyoid bone, and alternatively when the hyoid bone is fixed, the suprahyoid muscles are responsible for mandibular depression and retrusion of the mandible during opening of the mouth (20). They also play a role in chewing, and swallowing (20-22). The digastric muscles are one of many muscles that elevate the hyoid bone. If the suprahyoid and infrahyoid muscles fix the hyoid bone, it will tend to depress the mandible, and when the mandible is stabilized, the muscles elevate the hyoid bone, which is a necessary function for swallowing (21,22). The mylohyoid can slightly elevate the hyoid, the tongue,

The deltoid is not technically one of the four muscles directly related to the rotator cuff, but it’s a very important factor in the shoulder. If the supraspinatus is torn, the deltoid becomes the only shoulder elevator. When the deltoid is in use, the posterior and the middle of the anterior depending on the direction of the arm’s elevation, is typically used

Your rotator cuff consists of four muscles in your shoulder that allows you to move your arm away from your body. These muscles have tendons, which connect them to the head of your upper arm bone or humerus. When a tear occurs in these muscles, you will experience extreme pain on motion. A rotator cuff tear is also extremely painful at night. If left untreated, it may result in arm weakness.

This paper is going to be over rotator cuff injuries and what to do if this occurs to an athlete. The rotator cuff consists of four muscles which are the Subscapularis, infraspinatus, teres minor, and the supraspinatus and their associated tendons that insert into the Humerus. These groups of muscles are responsible for rotating the arm internally and externally as well as abducting the shoulder. The acronym for the four muscles of the rotator cuff is known as SITS. The best treatment for symptomatic, nontraumatic rotator cuff tears is unknown. The purpose of this trial was to compare the effectiveness of physiotherapy, acromioplasty, and rotator cuff repair for this injury. The way this trial worked was that 180 shoulders with the symptomatic,
